Step Up Transformer 100v

Yes, I have constructed a D.I.Y. power transformer that can be configured as a step up or step down transformer for my audio system. It can put out 104, 110 or 120 volts. As a bonus, it can also be wired to put out balanced power which makes a great sonic improvement to your system. When in the balanced mode, it can run up to a 9 amp load, and in unbalanced about 18 amps. I was first using it on an older tube amp to step down my wall voltage to 110 volts for the amplifier. I am now using it for standard 120 as a balanced transformer for my front-end. It is also quite affordable compared to other audiophile balanced power conditioners. I can fill you in more on the details if needed.

Thanks for the reply. I would like further details but I think I'm looking for something simpler. Maybe this unit will be good for my purposes:

The Electro-Harmonix EHU600 is the only step up transformer I have come across with a three pin socket for earth. Thanks!

The EHU600 is limited to 600W. Find the maximum draw of what you want to plug into that and double it. 600W is small for an amp. unless it's a flea watt.

I think BigShutterBug is referring to these:

And this is an enclosure that can fit up to the 2KVA model.

OK, thank you for the links. My amp - NaimUniti - is only rated at 50w. This could change in the near future to 80w. But I think the EHU600 is suitable for these ratings? Thanks!
